Computing system providing suggested actions within a shared application platform and related methods

ABSTRACT

A computing system may include at least one client computing device and a display associated therewith, and a server configured to provide access to a plurality of shared applications by the at least one client computing device, and extract text displayed by the shared applications on the display while the shared applications are being used by the at least one client computing device. The server may also be configured to generate a concept map associating the extracted text with actions initiated by the at least one computing device after displaying respective text on the display, and determine a suggested action to perform based upon text subsequently displayed on the display and the concept map.

BACKGROUND

Traditionally, personal computers include combinations of operatingsystems, applications, and user settings which are each managedindividually by owners or administrators on an ongoing basis. However,many organizations are now using application and/or desktopvirtualization to provide a more flexible option to address the varyingneeds of their users. In desktop virtualization, a user's computingenvironment (e.g., operating system, applications, and/or user settings)may be separated from the user's physical computing device (e.g.,smartphone, laptop, desktop computer). Using client-server technology, a“virtualized desktop” may be stored in and administered by a remoteserver, rather than in the local storage of the client computing device.

There are several different types of desktop virtualization systems. Asan example, Virtual Desktop Infrastructure (VDI) refers to the processof running a user desktop inside a virtual machine that resides on aserver. VDI and other server-based desktop virtualization systems mayprovide personalized desktops for each user, while allowing forcentralized management and security. Servers in such systems may includestorage for virtual desktop images and system configuration information,as well as software components to provide the virtual desktops and allowusers to interconnect to them. For example, a VDI server(s) may includeone or more hypervisors (virtual machine managers) to create andmaintain multiple virtual machines, software to manage thehypervisor(s), a connection broker, and software to provision and managethe virtual desktops. In some embodiments, a VDI server(s) may provideaccess to shared server-based hosted applications, as well asWeb/Software-as-a-Service (SaaS) applications.

Desktop virtualization systems may be implemented using a singlevirtualization server or a combination of servers interconnected as aserver grid. For example, a cloud computing environment, or cloudsystem, may include a pool of computing resources (e.g., desktopvirtualization servers), storage disks, networking hardware, and otherphysical resources that may be used to provision virtual desktops, alongwith additional computing devices to provide management and customerportals for the cloud system.

SUMMARY

A computing system may include at least one client computing device anda display associated therewith, and a server configured to provideaccess to a plurality of shared applications by the at least one clientcomputing device, and extract text displayed by the shared applicationson the display while the shared applications are being used by the atleast one client computing device. The server may also be configured togenerate a concept map associating the extracted text with actionsinitiated by the at least one computing device after displayingrespective text on the display, and determine a suggested action toperform based upon text subsequently displayed on the display and theconcept map.

In one example implementation, the at least one client computing devicemay comprise a plurality of client computing devices each with arespective display, and the server may be configured to extract textdisplayed by the shared applications across the plurality of computingdevices. The server may also be configured to generate an overlay on thedisplay including the suggested action, for example.

In accordance with another example implementation, the server may befurther configured to increase a weighting associated with the suggestedaction in the concept map based upon initiation of the suggested actionby the at least one client computing device. Furthermore, in an exampleimplementation at least one of the shared applications may comprise aWeb application, and the server may extract text displayed by the Webapplication via a Web browser plugin. In accordance with anotherexample, the server may be configured to perform optical characterrecognition (OCR) to extract text displayed by at least one of theshared applications on the display. By way of example, the actions mayinclude one or more of opening a service ticket and opening a calendarapplication, etc.

A related method may include using a server to provide access to aplurality of shared applications by at least one client computing devicehaving a display associated therewith. The method may further includeextracting text displayed by the shared applications on the displaywhile the shared applications are being used by the at least one clientcomputing device, generating a concept map at the server associating theextracted text with actions initiated by the at least one computingdevice after displaying respective text on the display, and generatingan overlay on the display including a suggested action to perform basedupon text subsequently displayed on the display and the concept map.

A related non-transitory computer-readable medium may havecomputer-executable instructions for causing a virtualization server toperform steps including providing access to a plurality of sharedapplications by at least one client computing device having a displayassociated therewith, and extracting text displayed by the sharedapplications on the display while the shared applications are being usedby the at least one client computing device. The steps may furtherinclude generating a concept map associating the extracted text withactions initiated by the at least one computing device after displayingrespective text on the display, and generating an overlay on the displayincluding a suggested action to perform based upon text subsequentlydisplayed on the display and the concept map.

Nos. 9,176,744 and 9,538,345, which are incorporated hereinby reference in their entirety. The '744 and '345 patents are bothassigned to the current assignee of the present disclosure.

Turning now to FIGS. 3-4 and the flow diagram 190 of FIG. 8, a computingsystem 30 and associated method aspects are first described. By way ofbackground, computer users are being faced with more and moreinformation every day, and the task of sorting and prioritizing what isimportant continues to become more difficult. For example, a user mayreceive many emails, some including attached reports. Users may also beexposed to numerous other media sources, such as internal/external webpages, yet they typically want to find and focus on just the informationthat is relevant to them or their job. Without suitable ways toefficiently “triage” such information, user productivity may be greatlyreduced—both in the time spent trying to triage the information, butalso in terms of valuable information which may be missed in theprocess. Yet, computer users often take the same repetitive action insimilar contexts upon receiving information that is important to them.Some of these repetitive actions are fully automatable, and others maybe assisted by automation.

Generally speaking, the system 30 provides a cross-platform,cross-application approach for automated learning of importantinformation that is presented to a user, as well as the repetitiveactions performed by the user in response to that information, so thatthese actions may be automated for the user going forward. The system 30illustratively includes one or more client computing devices 31 such asthose described above (e.g., smartphones, tablet computers,laptop/desktop computers, etc.) and associated display(s) 32. Thedisplays 32 may be integrated with the client computing device 31 (suchas in the case of a smartphone or tablet computer, for example), or maybe separate from the client computing device (such as a computermonitor, for example).

The system 30 further illustratively includes one or more servers, whichagain may be similar to those described above with respect to FIGS. 1-2,and in some embodiments may be implemented in a cloud computingconfiguration. Beginning at Block 191, the server 30 is configured toprovide the client computing devices 31 with access to a plurality ofshared applications 34, at Block 192. As will be discussed furtherbelow, the shared applications may be native applications published bythe server 30, Web application accessed through a shared browser,Software as a Service (SaaS) applications, etc. In accordance with oneexample implementation, Virtual Delivery Agents (VDAs) such as CitrixXenApp or XenDesktop may be used at the server 31 to provide access toshared applications and/or desktops, in cooperation with Citrix Receiverrunning on the client computing devices 31. However, other suitableprograms and systems may also be used in different embodiments.

The server 33 is further configured to extract text displayed by theshared applications on the display 32 while the shared applications 34are being used by the client computing device 31, at Block 192. In thisregard, the server 33 illustratively includes an extractor module orengine 35 which cooperates with the shared applications and/or clientdevices 31 to perform the text extraction, as will be discussed furtherbelow.

Additionally, the server 33 also illustratively includes a relevanceengine 37 which cooperates with the extractor 35 to generate a conceptmap 36 associating the extracted text with actions initiated by theclient computing devices 31 after displaying respective text on thedisplays 32, at Block 194. The relevance engine 37 is also configured todetermine a suggested action to perform for the user of the given clientcomputing device 31 based upon text subsequently displayed on itsdisplay 32 and the concept map 36, at Block 195, which illustrativelyconcludes the method of FIG. 8 (Block 196).

Generally speaking, a concept map defines suggested relationshipsbetween various concepts, which may be connected in a hierarchicalstructure. An example implementation of the concept map 36 is visuallyrepresented in FIG. 7, in which various concepts or key words are linkedto User B through linking phrases, which in this implementationcorresponds to various actions. Using the pertinent link phrases, theconcept map 36 may be implemented in a relational database model. Moreparticularly, in the relational database model, concepts in the map aredefined as entity types or attributes according to the link phrasesused. Linking phrases are also used to determine the type ofrelationship that exists between entity types. The concept map 36 mayaccordingly be implemented as a relational database model using adatabase engine such as SQL server, etc., for example.

The extractor 35, either on its own or in cooperation with theclient-side agent (e.g., Citrix Receiver) is able to capture all thetext that a user reads and writes during a computer session on theclient computing device 31. Using this this text, natural languageprocessing (NLP) techniques may be used to identify and map key concepts(e.g., project names, companies or people) in the concept map 36 alongwith actions taken in response to this key terminology. By iterativelyexpanding the concept map 36 for a particular user (or group of users),the relevance engine 37 may, over time, develop a weighting schemebetween these concepts (e.g., by assigning (and updating) weights to theconcepts within the relational database model). That is, the concept map36 represents how significant various concepts are to a particular useror employee with respect to different actions that person performs.

While the server 33 may perform text extraction and recommendappropriate actions for a user based solely upon a single user device 31using the shared applications 34, in the example illustrated in FIG. 3the server also learns important text and corresponding actions for theuser across different client devices. For example, the client computingdevices 31 may use iOS, Android, Windows, or other operating systems,yet the server 33 may continue to build and refine the concept map 36irrespective of which client computing device is accessing the sharedapplications 34. As such, the server 33 may advantageously build aconcept map for a give user account (here User A) incorporating his orher specific preferences and actions.

In accordance with the example implementation illustrated in FIG. 4, theclient devices 31 are associated with different respective user accounts(i.e., for User A and User B). That is, here the server 33 mayadvantageously learn actions associated with respective displayed textacross a larger user base sharing the applications 34. For example, thismay be appropriate for users in a call or help center, where manydifferent users field messages and perform the same tasks responsive tosuch messages. In this scenario, a relatively large group of users maytake repetitive actions in similar contexts. As such, the relevanceengine 37 may be used not just to increase efficiency of a single user,but also to “train” new staff, as the concept map 37 has already beentrained by other users to suggest the appropriate actions for specifickey words. In some embodiments, the server 33 may perform bothfunctions, that is, learning appropriate actions to automate orrecommend for a user based upon the user's own activities and actions,as well as the activities and actions of other users performing the sameor similar tasks. Moreover, this may be done across different platforms,such as for client devices operating on different respective networks.

Referring additionally to FIGS. 5-6 and 10, once the concept map 36 isestablished (and optionally trained for a number of cycles and/or aperiod of time), this understanding may be used to interpret newinformation that a user comes into contact with. When a user ispresented with new information (e.g. an email or a website) on thedisplay 32, the server 33 may highlight important sections of text (orpointers to information if not directly on the screen) that are believedto be important to the user.

In the example illustrated in FIG. 5, a shared email application isbeing used by User B (a member of an IT department), by which this userreceives a message 40 from User A. The message is regarding an Internetoutage User A would like help with, which includes keywords “Internet”,“down”, and “connection” which in the past have been found (in pastemails, text messages, chats, etc.) to precede User B performing anaction of generating a Level 1 service ticket to the XYZ InternetCompany. These words are highlighted in the message 40 by underlining(although other forms of highlighting, or no highlighting at all, may beused in different embodiments). As a result, these three terms have beenlinked in concept map 36 to User B by the action of generating a serviceticket (FIG. 7).

Moreover, based upon the prominence, frequency, etc., with which thevarious terms have been used, a relative weighting of their importancemay be assigned to them (Block 193 of FIG. 9). In the illustratedexample, both “Internet” and “down” are listed in the subject line ofthe email, and “Internet” and “connection” are both displayed in thebody of the email. In this regard, “Internet” is the most prominentterm, both in terms of being in the subject line, but also beingrepeated twice within the message 40, and “down” would be the secondmost prominent as it is in the subject line. In the concept map 36, thisweighting is visually represented by different text sizes (largersize=higher weighting), though it will be appreciated that in arelational database this may be done via a mathematical weight ormultiplier associated with each term.

In the present case, the relevance engine, upon being presented with theabove-extracted terms, will determine from the content map 36 that theappropriate action to suggest is opening a Level 1 service ticket, andfurther causes an overlay 38 to be presented on the display 32 askingUser B if this suggested action should be performed, at Blocks 197-198.If the answer is yes, then the relevance engine 37 may optionallyincrease the weighting associated with the above-noted terms, at Block199. If this suggested action is declined, the relevance engine 37 mayoptionally decrease their weight (Block 200).

In the example shown in FIG. 6, User B receives a message 40 asking forhis or her availability for a planning meeting week after next. As seenin the concept map 36 for User B, prior occurrences of the terms“meeting”, “week”, and “day” have resulted in the user opening acalendar application. Thus, the relevance engine makes this associationfrom the concept map 36 and provides the overlay 38 asking if User Bwants the calendar application opened. It should be noted that in someembodiments, actions may be automated without an overlay 38 or noticebeing provided to the user. For example, the user may be presented withthe option on the first occurrence, along with the option to alwaysperform this function responsive to the occurrence of these terms. Inanother example, once a particular weighting or confidence score isreached, or the suggested action has been accepted a certain number oftimes, the suggested action may be performed automatically without firstasking the user.

Highlighting of key terms and/or the overlay 38 may be achieved as anoverlay to a desktop and/or application implemented on top of the livecontent. In the above-noted implementation utilizing Citrix Receiver,the relevance engine 37 may cooperate with Receiver to provide theappropriate highlighting/overlays. Highlighting important informationmay help users become more productive, and serve to avoid importantinformation being overlooked. In some implementations, highlighting oroverlaying of text or suggesting actions may be performed based onstatistical or Machine Learning (ML) algorithms. These may also be usedto take user feedback into account, e.g., to perform weighting basedupon whether the user made use of the suggested actions, etc.

Further example implementation details of the extractor 35 and relevanceengine 37 will now be discussed. In an example embodiment, the extractor35 may be implemented using software running on the VDA (e.g., XenApp,XenDesktop, etc.) which extracts text that is currently displayed on auser's screen or display 31. The extractor 35 may parse the text andsubmit it to a Natural Language Processing (NLP) and/or Concept Miningalgorithm. NLP may be used to find keywords/topics in text that havebeen through optical character recognition (OCR). Example NLPimplementations which may be used include TF-IDF, TextRank and RAKE, forexample. Concept Map Mining serves to find and group conceptuallyrelated keywords. One example implementation may leverage a pre-existingor dynamically created thesaurus for this purpose.

The extractor 35 outputs a set of concepts with various weights. Theseare then submitted to the relevance engine 37 with the correspondingaction associated therewith. For example, the action may include a linkto the application/document/URL to be accessed. The extractor may beimplemented differently for different applications. For example, withrespect to Web apps, the extractor 35 may be implemented as a browserplugin which has direct access to all of the content on the page. Forother types of applications (e.g., native applications), the extractor35 may plug into the client access management program (e.g., CitrixReceiver) to snapshot a frame, identify blocks of text (e.g.,paragraphs), run those regions through OCR to extract a body of text,and run the NLP algorithm over that text, submitting the concepts withvarious weights to the relevance engine 37. The extractor 35 (or othercomponent of the VDA) may also extract one or more actions a user takes(mouse or keyboard input, application starts, file/URL opened, etc.)

In an example embodiment, the relevance engine 37 may receive a set ofconcepts from the extractor 35 with relevant weights associated with aparticular document/URL (or other actions). The relevance engine 37 addsinformation to the unique concept map 36, increasing weights of existingnodes, and links between related concepts, as discussed above. Using thesubmitted concepts along with the user's concept map 36, the relevanceengine 37 may establish: (a) whether any of the submitted concepts arehighly correlated; (b) whether any documents/URLs are highly correlated;and (c) whether any actions are highly correlated. The relevance engine37 may then return structured data to the caller, which includesconcepts that are believed to be highly relevant, along with one or moresuggested actions (e.g., related documents/URLs to be accessed).

With respect to generating highlighting or the overlay 38, variousapproaches may be used depending upon the type of application. Forexample, for Web and/or SaaS apps, the same browser plugin whichextracted text from the page may receive back from the relevance engine37 the concepts, links and actions believed to be relevant. The plugincan modify the page to add additional highlighting to regions of textrelated to those returned concepts. The plugin may also modify the pageto add additional on-screen links to the related documents/URLs returnedfrom the relevance engine. The plugin may also generate the overlay 38,and if triggered by the user, initiate the suggested action(s).

For native applications, the extractor 35 that submitted text to therelevance engine 37 for that region is returned a set of matchedconcepts along with related documents/URLs, etc. Using the example ofCitrix Receiver, a plugin may use an overlay display driver to draw ontop of the current screen over the region that was submitted if anymatching concepts are returned. This plugin may also generate theoverlay region 38 on screen which, if selected, will trigger a Receiverevent (rather than on the application). This event would result in acommand to launch a new application with a document/URL, or otheraction. The plugin overlays, and if triggered by the user, initiates thesuggested action(s).

In accordance with an additional use case, the server 33 may furthertrack behavior, responsive to which it may learn what operations aremost likely to occur after particular information is found. For example,navigating customer forums (e.g., in a shared Web browser application),it may be very common that an employee wants to go and create a ticketin a customer relationship management (CRM) program such as Salesforce.The server 33 may accordingly provide an overlay 38 to create a ticketlinking to that page and optionally pre-populating some of the fields.This may save the employee a significant amount of time.

In accordance with another example, the data sources used by the system30 may be extended to include platform specific “digital assistants”that employees may already be using. Such an assistant may provide helpeither in accessing important information (e.g., calendaravailabilities) or in offloading certain tasks queries.

Still another example use case for the system 30 is to implement anadditional layer of security that is independent from a particularapplication or OS. For example, the relevance engine 37 may detectatypical behavior from an individual or group, and flag up a suspiciousscore for further investigation by an administrator. One scenario wherethis may be beneficial is if a third party got access to validcredentials of another user.

In addition to extracting information from texts via OCR, the server 33may also process images and icons in a similar way. This may be ofinterest where graphical user interfaces allow users to triggerfrequently used actions using icons. An alternative implementation ofthe extractor 35 and overlay 38 may be supported by additional softwarerunning on the server 33 that actually provides the OS or applicationwith which a user interacts. This may be beneficial in that localApplication Programming Interfaces (APIs) may be used to either extractadditional information, or to perform relevant actions.

The above-described approach advantageously provides a single gateway tomany or all of the actions a user performs (e.g., an employee as part ofhis or her job) across different applications, and is able to determinewhat is relevant for the user and interact with the user's applicationsaccordingly. Moreover, through the use of the concept map 36, thepresent approach is able to determine relative importance, and toaccurately identify inter-dependent concepts.

By collecting and interpreting text that an employee is reading/engagingwith inside a shared application session, the system 30 mayadvantageously build a constantly improving/evolving understanding oftopics that are relevant to a user, and actions the user subsequentlytakes. The system 30 accordingly may provide assistive markers (e.g.,“call outs” or “quick actions”) that either draw attention toinformation that is particularly relevant, or actions that are likely tobe taken, as noted above.
